Turn signal and hazard light problems in my 2015 Foton Tunland

The indicator lights on the dashboard are blinking fast because there’s not the usual load on the indicator circuit from the exterior globes. This is a great way to know if you have a blown indicator globe, as the light on the dashboard will flash faster on the side of the failed globe.

So you need to look downstream to figure out why none of the indicator lights are getting power to them. This could be a broken wire, a body-computer problem, a poor earth or some other electrical gremlin that is robbing the lights of their power source and signal. An auto electrician would be a good place to tackle the problem.
